Patent DE-3613392-A1 (DE)
Title: Masonry-wall guide device for various masonry structures comprising artificial blocks
Inventor: FETTIG JOSEF
IPC: E04G21/18
Filed: 1986-04-21
Abstract: This masonry-wall guide is used to reduce the working time, which is very high in the case of laying small-format blocks. The directional tubes are aligned only once and permit much more accurate working than in the case of the conventional construction method. They are independent of weather and temperature. Since they can be produced cost-effectively, their acquisition is worthwhile for the erection of a single-family house. Moreover, savings are made in terms of skilled labour since laying the blocks no longer requires a great amount of skill. Laying using a bricklayer's line is dispensed with when use is made of this masonry-wall guide.
Patent DE-3624215-A1 (DE)
Title: Method for vibration-free gear changing in transmissions with hydraulically actuated friction clutches, and a clutch device suitable for this purpose
Inventor: BARTL MAX
IPC: F16H63/30
Filed: 1986-07-17
Abstract: The method proposed is intended to ensure vibration-free gear changing in transmissions with hydraulically actuated friction clutches, in which a first clutch of a first gear stage remains unpressurised or is depressurised and a second clutch of a second gear stage, which is to be coupled to a shaft, is subjected to pressure. During the process of clutching the second gear stage, the first clutch is initially subjected to a slight pressure and is only depressurised again when the friction elements of the second clutch are pressed together or when the shaft has achieved a certain speed of rotation. A clutch device suitable for this purpose has, in addition to the known pressure pistons for pressing together the friction elements, auxiliary and control pistons, of which the latter come into effect under the influence of centrifugal force. <IMAGE>

Title: Liquid-cooled transformer
Inventor: WANNER OSWALD
IPC: H01F27/02
Filed: 1986-08-11
Abstract: End walls (3) and longitudinal side walls (2) of transformer tanks which are filled with cooling liquid and form a rectangle in horizontal cross-section normally carry heat sinks (4) which are connected to the interior of the tank at least at their upper end and at their lower end in each case. According to the invention, one jutty (5) is in each case provided on the end walls (3) in an extension of the longitudinal side walls (2). This jutty (5) is connected to the interior of the tank and projects out of the end wall (3) just as far as the heat sinks (4) which are carried by it, each of the jutties (5) being fitted with heat sinks (6) in the same way as the respectively adjacent longitudinal side wall (2). In the case of tanks which are designed according to the invention for liquid-cooled transformers, the total cooling area which is available for heat-exchange cooling is greater than that in the case of tanks having the same width and length but having gaps at the corners of the tank which are not used for cooling, so that the design according to the invention makes it possible to achieve a greater rated power than in the case of previously normal transformers. <IMAGE>

Title: Gain-controlled light-emitting semiconductor structure, and a method for its production
Inventor: GOTTSMANN HARTMUT DIPL PHYS
IPC: H01S5/20
Filed: 1986-08-16
Abstract: The invention relates to a gain-controlled light-emitting semiconductor structure and to a method for its production. In this case, a narrow current path is initially produced with the aid of a V-groove diffusion technology which is known per se. The V-groove is subsequently etched away so that a planar contact-making surface is produced in an advantageous manner. Such a semiconductor structure is suitable, for example, for producing a semiconductor laser or an LED.

IPC: C13K13/00
Filed: 1987-01-29
Abstract: The invention concerns a process for production of L-arabionose in crystalline form. Starting material are extracted sugar beet pulp or other L-araban containing plant materials. These are heated in an autoclave as an aqueous suspension in the presence of Ca(OH)2. The so obtained solution is chromatographed on a cationic exchanger in the Ca-form. The araban containing fraction is hydrolyzed after adding H2SO4, neutralized and rechromatographed on a cationic exchanger in Ca-form. After concentrating the arabinose containing fractions L-arabinose is obtained in form of crystals by cooling crystallization.

Title: Infinitely variable conversion of torque for bicycles with power transmission by means of electrical conductors
Inventor: BALTZER SIEGFRIED
IPC: B62M23/00
Filed: 1987-06-11
Abstract: The invention relates to an infinitely variable conversion of torque for bicycles in which the transmission of the drive force from the tread crank to the rear wheel is effected by means of electrical conductors. The invention has the purpose of providing torque conversion which is problem-free to an extreme degree and absolutely safe. In order to achieve this object, the tread crank is connected to a generator with gear system. By means of the gear system, the generator is given the required speed of rotation. The rear wheel of the bicycle is connected to an electric motor. The electric motor transmits the drive force either to the tyre of the rear wheel or to the axle of the rear wheel by means of a roller. In the latter case, a downstep gear is required. A battery supplies the additional current when travelling over inclines in order to achieve the torque conversion. In addition, the battery supplies the power for lighting whilst travelling or stationary.
